ImportError: No module named _backend_gdk

Hello
I don't know why, but after switching from python2.5 to python2.6 I
cannot even launch matplotlib (matplotlib-0.98.5.3.win32-py2.6.exe).
This is what I get:

Traceback (most recent call last):

I have PyGTK installed. What can be the problem?
win xp sp3

I also use matplotlib-0.98.5.3.win32-py2.6.exe. It was built without
gtk. You have to build your own binaries with gtk support. Or find
compiled package (by Christoph Gohlke) with gtk support here:

http://www.lfd.uci.edu/~gohlke/#pythonlibs

and original information is here:

http://www.nabble.com/matplotlib-0.98.5.3.win32-py2.6.exe-td24299490.html

Personally I suggest use TkAgg. It dosen't matter if the figure window
is smaller than the canvas. If you don't resize the window (i.e. you
have checked the figure is ok and replotted the figure), it is ok to
just save it by clicking save icon in the toolbar.
